2. ' The Auk,' July and October, 1896. 



The July number opens with a paper by Mr. H. K. Job 

 on the Ducks of Plymouth co., Massachusetts ; Mr. Walter 

 Faxon gives details of the more interesting of the 200 

 drawings of the birds of Georgia made by John Abbot 

 between 1790 and 1810; Mr. O. Widmann remarks upon 

 the Peninsula of Missouri as a winter home for birds; 

 Mr. A. W. Anthony indicates the points wherein his ex- 

 perience differs from that of Mr. Leverett M. Loomis 

 respecting Puffinus opisthomelas ; Mr. A. H. Norton records 

 his observations on the Harlequin Duck in Maine ; Mr. 

 Kuthven Deane contributes some notes on the Passenger 

 Pigeon in confinement ; and Mr. D. W. Prentiss gives 

 an account of some birds met with in Bermuda. The 

 coloured frontispiece represents Lagopus evermanni, sp. n., 

 from Alaska, described by Prof. D. G. Elliot in the January 

 number, and named after Prof. B. W. Evermann (cf. Ibis, 

 1896, p. 410). 



In the October ' Auk ' the coloured plate is intended to 

 show the differences between two of the geographical 

 races of Ammodramus caudacutus, and illustrates a paper 

 by Mr. Jonathan Dwight, Jr. Mr. R. F. Young and 

 Mr. W. T. Bailey severally write on Pennsylvanian birds ; 

 Mr. Sylvester D. Judd discourses on the feeding-habits 

 of the English Sparrow and the American Crow, accentu- 

 ating the iniquities of the former species; Mr. H. C. 

 Oberholser critically examines the Mexican forms of the 

 genus Cerlhia; Mr. Abbott H. Thayer makes "Further 

 Remarks on the Law which underlies Protective Coloration " ; 

 and Dr. A. P. Chadbourne contributes a first instalment on 

 " Evidence suggestive of the Occurrence of ' Individual 

 Dichromatism' in Megascops asio." There are also two 

 papers which will interest ornithologists on this side, namely, 

 " Summer Birds of the Rhine," by Mr. Ralph Hoffmann, 

 and " The Cormorant-rookeries of the Lofoten Islands,^' by 

 Dr. R. W. Shufeldt, with a plate after a photograph taken 

 by Prof. Collett. It is pleasant to find our American cousins 

 taking notice of Palsearctic birds.
